Abstract

A chamfering mold technology was brought forward to remove the transverse corner crack of continuous casting slab. Numerical simulation and industrial experiment of chamfering mold show that the corner temperature of chamfered slab can be increased more than 70℃ at straightening section, which escape the high temperature inductile zone of steel. At the same time, the structure of bevel edge can decrease the Z-direction stress of continuous casting slab to control the transverse corner crack.

Key words
